Moreover, if boron ions are implanted, a peripheral tunneling between the external base and the emitter is suppressed. Thereby, a process is simple, the formation of an element is facilitated and the efficiency and yield of the element are also improved.

Title: Method for generating alteration information on environment element in system environment
Inventor: NAKAMURA TAKAFUMI
IPC: G06F9/06
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To accurately record parameter alterations of the system environment and to easily find the cause of troubles in such a case by comparing the records one generation before with the records of the current generation in response to abnormality of the system or an instruction for difference information generation from an input means. SOLUTION: A record generation part 1 generates a new record based on the altered environmental elements. Then the record before the alteration is held as a one-generation-precedent record 4' and the new record is held as a current-generation record 4. An abnormality detection part 7 once detecting abnormality of the system informs a difference generation instruction part 6 of the system abnormality. The difference generation instruction part 6 instructs a difference generation part 5 to generate differences and the difference generation part 5 takes the one-generation-precedent record 4' and current- generation record 4 out of a record hold part 3 to find their differences. Then parts where no environment element is altered are removed and environment elements of the current generation of the altered part and operation information are extracted to generate a difference record.
